KHACHIMO DPS-400AB-12A 400W ATX power supply

SKU CH-5DE6-9SEZ2

An 80 PLUS Gold ATX power supply delivering 400W with Modern Standby support, Zero RPM fan mode, and resonant LLC topology for quiet, efficient power

  • Product typeATX
  • Faster wake-from-sleep with Modern Standby support
  • 80 PLUS Gold efficiency cuts power draw and heat
  • Fan stops at low load for silent running
  • LLC resonant plus DC-to-DC topology delivers clean power
  • 400 W ATX output fits compact 1U builds

Compact ATX power supply for small-form-factor

The KHACHIMO DPS-400AB-12A delivers 400W in a 1U form factor that fits tight chassis such as NAS enclosures and slim workstations. Its 80 PLUS Gold certification ensures high efficiency at typical loads, reducing waste heat and keeping electricity costs lower for always-on systems.

Fits standard ATX layouts while freeing internal

The unit uses a conventional ATX connector set so it plugs directly into mainstream motherboards without adapters. Because the 1U height leaves more clearance above the motherboard, builders gain space for taller CPU coolers or additional drive cages in compact cases.

Sustained output with quiet thermal behaviour

Resonant LLC topology with DC-to-DC conversion maintains clean voltage regulation during continuous operation, limiting ripple and coil whine. At low and medium loads the fan stops completely, and Modern Standby compatibility allows the system to enter deeper sleep states without losing responsiveness.
